# Use `UpdateMaintenanceWindow` with an Amazon SDK or CLI
<a name="example_ssm_UpdateMaintenanceWindow_section"></a>

The following code examples show how to use `UpdateMaintenanceWindow`.

------
#### [ CLI ]

**Amazon CLI**  
**Example 1: To update a maintenance window**  
The following `update-maintenance-window` example updates the name of a maintenance window.  

```
aws ssm update-maintenance-window \
    --window-id "mw-1a2b3c4d5e6f7g8h9" \
    --name "My-Renamed-MW"
```
Output:  

```
{
    "Cutoff": 1,
    "Name": "My-Renamed-MW",
    "Schedule": "cron(0 16 ? * TUE *)",
    "Enabled": true,
    "AllowUnassociatedTargets": true,
    "WindowId": "mw-1a2b3c4d5e6f7g8h9",
    "Duration": 4
}
```
**Example 2: To disable a maintenance window**  
The following `update-maintenance-window` example disables a maintenance window.  

```
aws ssm update-maintenance-window \
    --window-id "mw-1a2b3c4d5e6f7g8h9" \
    --no-enabled
```
**Example 3: To enable a maintenance window**  
The following `update-maintenance-window` example enables a maintenance window.  

```
aws ssm update-maintenance-window \
    --window-id "mw-1a2b3c4d5e6f7g8h9" \
    --enabled
```
